PHP — популярный язык сценариев общего назначения, особенно подходящий для веб-разработки.

The php_next_marker function in image.c for PHP 4.2.2, 4.3.9, 4.3.10 and 5.0.3, as reachable by the getimagesize PHP function, allows remote attackers to cause a denial of service (infinite loop) via a JPEG image with an invalid marker value, which causes a negative length value to be passed to php_stream_seek.

Integer overflow in the exif_process_IFD_TAG function in exif.c in PHP before 4.3.11 may allow remote attackers to execute arbitrary code via an IFD tag that leads to a negative byte count.

PHP 4.x to 4.3.9, and PHP 5.x to 5.0.2, when running in safe mode on a multithreaded Unix webserver, allows local users to bypass safe_mode_exec_dir restrictions and execute commands outside of the intended safe_mode_exec_dir via shell metacharacters in the current directory name. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

The addslashes function in PHP 4.3.9 does not properly escape a NULL (/0) character, which may allow remote attackers to read arbitrary files in PHP applications that contain a directory traversal vulnerability in require or include statements, but are otherwise protected by the magic_quotes_gpc mechanism. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

Multiple integer handling errors in PHP before 4.3.10 allow attackers to bypass safe mode restrictions, cause a denial of service, or execute arbitrary code via (1) a negative offset value to the shmop_write function, (2) an "integer overflow/underflow" in the pack function, or (3) an "integer overflow/underflow" in the unpack function. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

Buffer overflow in the exif_read_data function in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to execute arbitrary code via a long section name in an image file.

The safe mode checks in PHP 4.x to 4.3.9 and PHP 5.x to 5.0.2 truncate the file path before passing the data to the realpath function, which could allow attackers to bypass safe mode. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

The deserialization code in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to cause a denial of service and execute arbitrary code via untrusted data to the unserialize function that may trigger "information disclosure, double-free and negative reference index array underflow" results.
